Normally only when I've reinstalled glibc and got it wrong.

(I do such work in chroots, normally, so I can just attack it from
outside the chroot; but I can imagine disk damage or something killing
the ld-linux.so.2 symlink or something like that... and then it'd be
useful. --- not *very* useful, mind you, because there's always sln(1),
but without sash, the ld-linux.so.2-with-args trick or a statically
linked ls(1), it can be hard to see what's actually gone wrong.)
